Answer : Air Header is a series of multiple valve assemblies that operate from one originating point. air header manufacturers in India designed these valves in a way that they can accommodate various valves. The inlet connection of the valve has multiple outlet connections. The air header is the main trunk line in a compressed air system that carries compressed air from the compressor to airdrops located in a plant, or distribution center like a petrochemical loading terminal. Air Header act as a distribution manifolds that provides users with many connection options for isolation manifolds. It can be used with various outlet-take-off valves. This Air Distribution Header is a very efficient machine to replace many unit valve assemblies, operating from one source.
Answer : Ball valves are quarter-turn on/off devices. A pivoting ball in the center of the valve controls the flow of liquid or gas media. The pivoting ball is known as a rotary ball, and it is designed with a hole (a bore) in the center. A stem on the top of the ball rotates the ball to open or close the valve. In special versions, ball valves are also used as a control valve. This application is less common due to the relatively limited accuracy of controlling the flow rate in comparison with other types of control valves. When the cross-section of the bore is perpendicular to the area of the flow, the fluid is not permitted to pass through the valve. The fluid flows through from the valve, and the fluid flow rate depends on the area of the bore exposed to the floor.

Answer: A double ferrule compression fitting is the most common instrumentation style fitting. They are regularly used in process measurement and control systems in aerospace, defence, chemical processing plants, medical equipment and oil & gas industries. Compression tube fittings compress one of the fitting’s components into another, typically tubing, to form a watertight seal between two separate lines. The compression fitting has been used less often in the water treatment industry with the advent of quick-connect type fittings, but it is still an excellent fitting that can bear high pressure and provide a dependable, tight seal. A compression fitting comprises three parts: a sleeve, a nut, and the fitting body itself. When the nut compresses the sleeve into the relevant body, it functions as a seal. The working pressure of the fittings is very high. Seeing as it is constantly put through very regular flow in the system, the fittings need to be extra strong in order to go through a lifetime.
Answer: Condensate pots are used as a barrier between the main line and the secondary instruments in the measurement of steam or other vapors which condensate to a liquid state insuring compatibility with the secondary instruments. They can also be used to cool down very high temperature liquids. The main use of condensate pot is for maximizing the accuracy of differential pressure flow measurement on steam (or vapor) applications. Between the pot and the differential pressure transmitter is water (liquid) which eliminates any measurement errors due to a liquid/vapor mix at the measurement device. In order for this to work correctly, both high pressure (HP) and low pressure (LP) impulse lines should be the same length. Thus, eliminating pressure head errors. One condensate pot will be required for each impulse line.
Answer: Manifolds are used extensively throughout the oil and gas industry for the distribution of gases and fluids. They are designed to converge multiple junctions into a single channel or diverge a single channel into multiple junctions. A manifold is a wide and/or bigger pipe, or channel, into which smaller pipes or channels lead. A pipe fitting or similar device that connects multiple inputs or outputs. A piping manifold can be used for various purposes such as distributing fluid from a main pipe to several smaller pipes, controlling the flow of fluid to different parts of a building or industrial facility, or isolating a section of a pipe system for maintenance or repair.
Needle valves are commonly used to control flow and protect delicate gauges from damage caused by sudden pressure surges of liquids and gases. They're ideal for systems using lighter and less viscous materials with low flow rates. needle valve’s plunger has a tapered end that raises and lowers with the spin of a handle to open or close an orifice. Needle Valves, sometimes referred also as Plunger Valves, are regulating valves and enable engineers to finely control and regulate fluid flow and pressure. Needle valves are similar to the globe valve in design with the biggest difference is the sharp needle shaped disk. Needle valve have a small port and a threaded needle-shaped plunger. This arrangement permits a very gradual increase or decrease in the size of the opening allowing precise regulation of flow, although it is generally only capable of relatively low flow rates.
Needle valves can operate manually or automatically. Automated needle valves are connected to a hydraulic motor or an air actuator that automatically opens and closes the valve. The motor or actuator will adjust the plunger’s position according to timers or external performance data gathered when monitoring the machinery. Both manually operated and automated needle valves provide precise control.
A non-return valve allows a medium to flow in only one direction and is fitted to ensure that the medium flows through a pipe in the right direction, where pressure conditions may otherwise cause reversed flow. The main importance of non-return valves is their working of allowing flow in the downstream direction and preventing the flow in the upstream direction.
Pipe fittings are widely demanded for any piping and plumbing systems used in industrial and commercial applications. Fittings allow pipes to be joined or installed in the appropriate place and terminated or closed where necessary. Fittings are available in various shapes and sizes. They can be expensive, require time, and different materials and tools to install. They are an essential part of piping and plumbing systems. There are thousands of specialized fittings manufactured. Each type of pipe or tube requires its own type of fitting, but usually all pipe fittings share some common features.

Quick release couplings are fitting are used to mate fluid lines with system equipment that requires frequent connecting and disconnecting. They are used in both pneumatic and hydraulic applications to build or discontinue the connection of a fluid pipeline. quick disconnect couplings allow the connection and disconnection of fluid lines in a fast and convenient way, without loss of fluids.
They provide the users the ability to rapidly connect and disconnect hydraulic hoses to machines or attachments. All quick disconnect couplers have two parts: a male half and a female half. When connected properly, these parts seal and the fluid flows, tackling internal pressures and resisting any forces that tend to pull the joint apart. The parts are easily disconnected without tools by disengaging a locking mechanism. Hydraulic quick disconnect couplings are precisely engineered for specific fluid applications.
A safety valve protects a system against overpressure. Overpressure occurs when the system's pressure exceeds the Maximum Allowable Working Pressure (MWAP) or the pressure for which the system is designed. Safety valves can open very quickly compared to relief valves. A safety valve opens from a set pressure; the valve first opens a little, then opens fully so that the unwanted pressure is removed from the system as quickly as possible. A safety valve can be considered as a pressure reducing or pressure removing device. When there is any excessive internal fluid pressure then this valve would open so that the damage in the system can be prevented. These valves are commonly used in gas and steam lines. In an unprotected pressure vessel or a system if the pressure level exceeds the safe pressure level, then there could be catastrophic effects on both plant and personnel.
The major purpose of a safety relief valve is to protect any pressurized system from the effects of exceeding its design pressure limit. These valves are designed to automatically discharge gas pressure or liquid from any pressure-containing system and thus it prevents excessive pressure and protects plants and personnel. In order to fulfil all this, a safety valve should be properly sized, selected, installed, and maintained.
Y-Strainers are devices for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. They are used in pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment. A Y strainer mechanically removes solids and other particles when fluid flows through it. They are essential in numerous fluid control applications to ensure that particles within the fluid do not negatively affect any downstream component. In this article, we will review their design, use cases, how to size the mesh filter, materials, and how to clean them.
Siphon, also spelled syphon, instrument, usually in the form of a tube bent to form two legs of unequal length, for conveying liquid over the edge of a vessel and delivering it at a lower level. Siphons may be of any size. The action depends upon the influence of gravity (not, as sometimes thought, on the difference in atmospheric pressure; a siphon will work in a vacuum) and upon the cohesive forces that prevent the columns of liquid in the legs of the siphon from breaking under their own weight.
